I bought a HP Compaq 6730b that ran XP off of Craigslist and it worked great but the hard drive went bad so I bought a new one. When I went to install the new hard drive I wanted to go into the Bios to change the settings to boot from the DVD drive to install windows 7 (figured I would upgrade the OS) and found out the Bios is locked. I tried to call the guy but his number didn't work anymore. So I google searched " bios unlock 6730b". I have tried to reset the bios by pulling out the RTC (real time clock) battery and waiting 5 minutes and starting it back up but still no results. It will let me try to install XP and then goes straight to BSOD after loading some files. I even tried to boot SLAX linux from the DVD drive but that fails too. Is the Bios locked to that OS?
I read some where that the bios can be locked to a certain OS and there is a file on the hard drive that checks the file on the bios to make sure its the same. Much thanks for any info.
